JOINTER TABLE AND OPERATING MEANS THEREFOR.

Application filed February An object of this invention is to provide improved meansI for adjusting the altitude this invention is in respect of altitudinal adjustment.

My invention consists in the constructi arrangement and 'ointer or similar locking and tables in any selected alt-ifor supporting a machine,

combination of elements hereinafter set forth, pointed out in the claims and illustrated drawing', in which- Figure 1 is a ilan and Figure vation of a gointer embocying ments. Figure 3 is a side elevation,

in section, on

by the accompanying 2 side elemy improvepartly an enlarged scale, of one table of the ointer showing my improvements applied thereto. Figure of the same. Figure 5 is a detail section 4 is an end elevation the indicated line 5-5 of Figure 3. lFigure 6 is a hinges. Figure 7 is a perspective of one the T-plates employed in the machine.

ln the construction of the machine shown the numerals 10, 11 `designate bars connected bars 12, 13 and adapted to ly in bench. stuid or support not shown.

forming the lower portions of and supporting tables 25, 26. The tables 25, 26 and their supporting angle bars 23, 24 are rigidly connected and are placed end to end and spaced apart, their adjacent ends being beveled or curved and adapted to overlap a cutter 27 carried by a shaft 28 journaled in suitable bearings 29, 30 on the angle bars 10, 11, one end portion of said shaft carrying a pulley 31 or lsuitable device whereby the shaft may be rotated by a power connected therewith (not shown). The eight hinges, four for each table, support the tables on each side, near each end and in parallel relation with the angle bars l0, 11 at all times. T-plates 32, 33 are provided with bolt holes in the end portions of their heads adapted to receive bolts 34 whereby they may be secured to and depend from central portions of the respective tables 25, 26. The stems of the T-plates 32, 33 extend transversely of and partially across the respective tables 25, 26 and are formed with vertical slots or notches 35, one slot in each stem. Bearing plates 36, 37, of angular form, are mounted on the central portions of the cross-bars 12, 13 respectively. Each bearing plate 36,v 37 is formed with bolt holes side by side in its base adapted to receive bolts 38 to fix it to its cross-bar. The upright portionv 39 of each bearing plate is rounded on its top and is formed with a threaded aperture having its axis parallel with and below the median line common to the tables 25, 26. Feed screws'40, 41 are threaded in the apertures of the upright portions of the bearing plates 36, 37 and extend in opposite directions therefrom. Each feed screw 40, 41 is'formed with a reduced inner end portion 42, merging into the body of the screw by a conical shoulder 43 and is adapted to extend through a slot 35 in the stein of a T- late 32 or 33 loosely. A washer 44 is mounted on each feed screw and is formed with a conical hole adapted to receive and form a bearing for the conical shoulder 43 on the screw, said Washer bearing against the outer face of a stem of a T- plate. A washer 45 is mounted on the reduced portion 42 of each feed screw and bears against the inner face of a stem of a T-plate.

.lamb or locking nuts 46, 47 are mounted on threaded portions of the reduced" thereby swivel the n feed screws in said plates; the relation of the screws and washers to the plates being` loose in order that the stems of said plates may rise and fall in respect of the screws. fr set collar 48 is mounted on each feed screw 40, il out-side of the bearings therefor, whereby to limit and determine inward movement of the screws relative to the bearings. A crossthead or turning pin 49 is mounted inand transversely of the outer end portion of each feed screw 40, lll, whereby `manual force may be applied to turn the screws either direction.

In practical use the tables 25, 26 are adjusted independently through rotation of the respective feed screws 40, 4l and the movement of rotation of the screws is transmitted through the stems of the T-plates to reciprocation of the stems and tables, thereby moving the table through arcs but at the same time maintaining the level position thereof. Thus the tables are raised or lowered relative to the cutter' 27 to regulate and determine the depth of cut thereof on an object, such as a plank, moved across the cutter in contact with the tables. It is the function of the hinges described to permit the movement of the tables through arcs relative to the angle bars l0, 1l and at the same time maintain the parallel relation thereof.

l claim as my inventionl. A jointer table and operating means therefor adapted to be mounted on a support, comprising a base frame formed of spaced, parallel side members connected and spaced by transverse bars rigidly secured thereto; a. rotary cutter mounted transversely of the central portion of said frame in bearings carried by said side members; angle plates carried by both of said side members and having links pivoted to and rising from their upper ends; tables pivotally supported between the upper ends of said links, spaced from and parallel with said side members:

Leos/,eso

and means comprising a yoke depending from each of said tables, a threaded standard at either end of said frame and a feed screw passing through the threaded portion of said standard and engaging said yoke, whereby said tables may be manually moved through an arc, vertically.

2. ln a jointer table, the combination of a base frame adapted to be secured to a support, a cutter head mounted for rotation transversely of the central portion of said frame, spaced, opposed angle plates carried by said frame at either side of said cutter head, links pivotally secured to and rising from said angle plates, tables pivotally supported between the upper ends of said links, said tables being formed of spaced, parallel side members overlain'and connected by a top plate, together with manually-operable feeding means connecting said tables with either end of said frame whereby said tables may be caused to move, separately, through al vert-ical arc.

3. in a jointer table having a base frame adapted to be secured to a support, a cut-ter head mounted for rotation transversely of the central portion of said frame and link supported tables at either side of said cutter head, above, parallel with and verticallyv ustable relative to said frame, the combination of an independent feeding mechanism for controlling the adjustment of each of said tables comprising an open-ended yoke depending from each of said tables, a

i lard carried by either end of said frame beneath the outer end of each table, a manually-operable feed screw in threaded engage` ment with each of said standards parallel with and longitudinal of said frame and means on the inner end of each feed screw for sliding engagement with the arms of said yoke.
